CAR-COUPLING.

K SPECIFICATION forming part of Letters Patent No. 698,433, dated April29, 1902.

Application filed February 15, 1902. Serial. No. 94,259. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID L. BOOK, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in Car-Couplings; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to car-couplings, has especial reference to thatclass of couplings known as the Master Oar-Builders or Janney type forautomatic coupling, and has for its object certain improvements inconstruc tion, which will be fully disclosed in the followingspecification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a top plan view with the head of the coupling intransverse or horizontal section, showing the hook or knuckle inposition for automatic coupling;Fig. 2, a perspective, on an enlargedscale, of the front part or head of the coupling with the hook and thelatch removed; Fig. 8, a like view of the hookdetached; and Fig. 4:, alike view of the latch, also detached.

Reference being had to the drawings and the letters thereon, A indicatesthe body. of the coupling, provided with slot at for the reception ofthe usual draft-pin and a shoulder 1), which engages the timber of acarframe; B, the head of thecoupling, which is provided with lugs c c,to which the hook or knuckle C is pivotally secured to swing laterallytherein, a recess dto receive the tongue 6 of the hook, a hornf, and ashunting-seat g, inclined toward the horn to facilitate coupling whilecars are standing on or rounding a curve in a road-bed.

The hook Cis provided with a laterallyreduced member h, which engagesthe lugs c c and is secured in position by a pin a, which passes throughthe lugs and the hook and has a recess 7c in the rear side of thetongue, forminga transverse shoulderl,which takes part of the strain ofthe draft in pulling and part of the shunting effect in pushing a car ora train of cars. Part of the shunting effect is also taken up by thefaces m and n on the tongue 6 and the corresponding faces up in therecess d.

The head B is provided with a side D, which is approximately parallelwith the line of draft and may therefore be called straight incontradistinction to the curved or rounded heads in common use, and inthis side of the head a pocket gis formed, having shunting shoulders orseats r r and s, the latter beingat the rear end of the pocket, and inthis pocket a laterally-swinging latch provided with lateral extensions1' 1", which engage the seats '1' r at the rear ends of the extensions,is pivotally secured by a pin 16, and the flat part it of the latch infront of the pin t is held in engagement with the fiat rear side 0), andthe end w of the latch is held in engagement with the shoulder Z of thehook C by a spring w in said pocket q under the rear end y of the latch,and the end 2 of the latch engages the seat 8 of the pocket as a furtheror additional draft and shunting resisting medium.

The latch E is drawn out of the pocket at its front end to release thehook C for un-.

coupling by any suitable means, such as an eyebolt z, to which a rod orchain (not shown) may be attached.

The coupling is designed on such lines as to couple with the prevailingtype of couplings and to work in conjunction therewith without unduestrain on either,

Having thus fully described my invention, what I claim is- 1. Acar-coupling having a head provided with a side approximately parallelwith the line of draft, a pocketin said side having shunting-shouldersin the sides of the pocket, and a laterally-swinging hook having atransverse shoulder, in combination with a laterally-swinging latchlying within andjpivoted in said pocket with its front endnormallyengaging the shoulder on the hook,and having lateral extensionsengaging said shuntingshoulders.

2. A car-coupling having a pocket in the side of the head provided withshunting-shoulders in the sides and at the rear end of the pocket, and alaterally-swinging hook having rear end engaging the rear wall of saidpocket,

a transverse shoulder; in combination with a and an inelosed springengaging the latch. 10 laterally-swinging latch having lateral and Intestimony whereof I aflix my signature rearward extensions, lying withinand pivin presence of two witnesses.
